OPTOMAN mirrors for the Mid-IR spectral region feature high spectral performance and low absorption. Although scattering might not be a significant issue when speaking of Mid-IR optics due to the long wavelengths, absorption remains a serious concern because it leads to reduced Laser-Induced Damage Threshold (LIDT).

OPTOMAN concentrates solely on the most advanced sputtering technology - Ion-Beam Sputtering (IBS), which offers many great capabilities in depositing thin film coatings with great uniformity and bulk-like density. IBS solves key problems for Mid-IR coatings by:

Improving coating density, ensuring long-term durability in harsh and dynamic environments.

Minimizing absorption losses, which helps optimize the output power of lasers.

Improving LIDT and enabling operation at high-power levels.
